The First Ultraviolet Studies of the Optical Candidate for the X-Ray Source 1118-61

Coe, M. J.; Payne, B. J.

The X-ray pulsator, 1118-61, discovered in 1975 by the Ariel-5 satellite, has been observed for the first time at UV wavelengths using IUE. Its UV spectrum clearly identifies the optical counterpart as a Be star similar to that seen in other X-ray pulsators. From the 2200 Å absorption feature a distance estimate of ∼ 4 kpc is obtained and the carb…

More on theλ2800 Å `interstellar extinction' feature

Nandy, K.; McLachlan, A.

We respond to comments made in a recent letter by Karimet al. (1984), and show that the examples of interstellar absorption atλ2800 Å that they have presented so far can all be attributed to overexposure of the IUE detectors.

Epsilon Aurigae

Chapman, R. D.

In April 1984, fourth contact ended the two year long eclipse of Epsilon Aurigae. An astrometric study of the study of the system was carried out by Van de Kamp (1978) leading to the conclusion that the orbit is seen very close to edge on. The eclipse was monitored by a number of groups from the ground and from spacecraft such as the IUE. Ultravio…
